This student campaign invites a closer look at Singapore's reefs and the life they support. Singapore's coral reefs are found mainly around its southern islands.

The optional comparison imagines possible long-term reef damage. Bleaching does not mean instant death: bleached corals can be alive and some recover. Fish responses vary. Loss of living coral and later erosion of reef structure can reduce food and shelter; damage to the reef’s structure can also weaken its wave-buffering role. The comparison shows two illustrated conditions. Recovery takes sustained care.
